[openamq-dev] porting to Ubuntu

[Jonathan Schultz]

Nick,

Congratulations you seem to have stumbled on a hitherto undetected race 
condition in the SMT initialisation code.  I'll come up with a patch for

Out of interest, can you tell us what hardware and kernel version you 
are using?

Regards,
Jonathan
